I was unzipping multiple .rar files on Mac with OS 10.13.1. Something went wrong and I deleted the extracted files and the zip folders. But now, I can see that lot my storage space on my back is occupied.

On further investigation I noticed that the space is occupied in Users folder. But the folders and file size in the Users do not add up to that size.

Where can I see these hidden files, certainly these are created by Keka in the extraction process.
